Old-time canners can be allergic to change

How often do we hear, “my grandmother taught me to can and I have been canning for 40 years.”

Elizabeth Andress, head of the National Center for Home Food Preservation, has identified a reluctance in old-time canners to update their methods when they should:

Various studies through the years show consumers .. not willing to change from old methods when science updates indicate new needed.”1

People just don’t like change (unless of course it’s them foisting it on other people.) They get comfortable in their ways, saying that they “ain’t killed anyone yet” and they resent new information that challenges the thinking and habits that have “worked just fine” for them. Even back in 1988, canners were complaining about the changes that were new then:

Many people say, ‘Well, I’ve been canning tomatoes all my life and I’ve never had a problem yet, so don’t think I’m going to change my methods.’ The research was not done to irritate people and try to make them change for the sake of change. It was done to provide home canners with the safest methods and processing times possible for canning. You know, the experienced canner only has to make a mistake one time in processing and that may be their last time. Home canning is safe and easy to do if a person follows the USDA’s recommended guidelines. Home canning is not the place to alter recipes and experiment with processing times.”2

You are never too old to learn something new, and it’s only when you stop learning that you start to grow old.

Given the chance, who wouldn’t want to learn something new about a hobby or practice they love?

Canning has evolved a lot in the past several decades

Canning is a science: we all might be getting old, but if our knowledge is, too, that’s a problem.

Canning is a modern science that is still evolving, not a traditional one that was settled centuries ago. No one was doing home canning back in Rome or medieval monasteries, so this is not an area in which “tradition” counts.

And while it’s true that actual science doesn’t change, our understanding of it does as we learn more about the underlying truths and fundamentals. On many things, the understanding of the science in the 1930s canning books was very wrong.

Linda Harris cautions that what you knew to be true years ago may no longer be the case:

Getting a better and better understanding of the science behind home food preservation is an ongoing process. Sonja Loukel at the University of Alaska says:

Research on food preservation is an on-going process. United States Department of Agriculture, and the Cooperative Extension Service continuously apply new research findings to their recommendations for food preservation techniques. The goals are to both increase food safety and improve food quality.”4

Crystal Futrell of the Kansas State University Extension says,

Canning is a science that changes over time: the hardest thing for many to understand is that canning is a science that’s continually being researched and updated, and over time. The rules change. The best way to stay updated on the rules is to only use current recipes from credible sources.”5

Yes, it can be annoying to have to learn new things. But when safety and quality are at stake, it’s a must. And, it keeps you young. Photo credit: Gerd Altmann / Pixabay.com / 2014 / CC0 1.0

Did time slip by on you and leave your canning knowledge behind?

The years fly, and there can be so many things to keep up with in daily life.

Do not let your pride be hurt that just bottling your hot jam without processing the jar (known as ‘Open Kettle Canning‘) has been pronounced unsafe.

That kind of canning for jam was still advocated as recently as the early 1980s, so you just learnt what they told everyone back then. You weren’t doing anything differently from anybody else.

They now warn against that practice because enough problems with illness, as well as consumer complaints about spoilage and wasted expensive fruit, have cropped up and been documented.

So don’t blame yourself, you can blame the authorities for not researching faster back then.

When you get caught up, give yourself a firm pat on the back, and help others to, as well!

Keeping up with the times may not always be good in all things, but in home canning it absolutely is, and it ensures that the wisdom you have to impart to people is informed with the latest news and techniques, so you truly are preparing them for the future.
